MFSL CD's - Are they worth it?

I have quite a few MFSL CD's I've gotten over the years. On most remasters they sound markedly better than the original releases. I have gotten a few recently, however, that DON'T sound as good as the original. Case in point, U2's Joshua Tree. A little too warm and boomy when compared to the original also a lack in detail. As these CD's are becoming more expensive do you think they are worth the $? Do you like them?
